Working class today

During the time of Marxism, Karl Marx wanted the working class to one day rise against the ruling class. Today we don't have necessarily have a ruling class but the working class still remains. I wouldn't consider a doctor or a lawyer working class but there are many immigrants in this country who work just to put food on the table and they barely make enough money to do that. People get payed off the books and make under minimum wage and work in bad conditions and in unsafe places. Therefore, do people still agree with Marxist theories now? Is there even the slightest chance that this working class will one day rise up against their authorities?
